I'd really like to see some pix of any Subaru rigs y'all may have as I'm think'in on gett'in a WRX & I'll be haul'in around a Revolution and a Outback so I am very interested in this topic as well.
My Thule rack bars are 65" long. The Thule cross bars mount on my factory WRX roof rack bars, assuming you buy the active sports person WRX model, not the family person style with the trunk. You do have to remember the racks presence when getting out the car, they are head clunkers. I believe Thule still sells rack bars that are longer than mine. In my state, the only maximum width rule I know of is 96 inches on all roads, and 102 inches on certain federal roads. The large cargo area is how I carry my i12S Hobie kayak inside the WRX. I suspect you could carry your Revo flat and the Outback on it's side, but check the measurements for yourself first.
I could not figure out how to attach a photo here of the Thule racks on my bugeye WRX, PM me and I'll send it to you. How did you do you photo JimL? Nice rack, BTW.
The WRX is a great all purpose car for an active lifestyle person, roomy front seats and cargo area (with the back seats flipped down), very fast, zips around corners without rollover worries, and gets upper twenties mpg. Very reliable, and the "wagon" model is inexpensive to insure. The 02 to 07 models tow a 1000 lb trailer with ease too, they are rated to 2000 lbs with trailer brakes. Don't buy a no clutch pedal transmission, they are gutless off the line. Don't buy an 08. The 08 models lost their punch, 09 & 10's have it restored. And of course, a WRX should be World Rally (X)cross blue
